Hispanic American Indians are a vulnerable community in the US and very little is known about the first comers and first-generation of migrants. Table 1 shows basic statistics for IMLA, illustrating that 67.7% (SE=4.3%) of the participants in the survey were females with a sizable number of women being the household head. Income was low across the sample; we dichotomized this variable as less than $25,000 and $25,000 or more with a staggering 71.2% (SE=4.1%) of households reporting annual earnings below $25,000. Our sample also reported that 64.5% of these families have two or more kids and that 80% of the participants were Catholics. Seemingly, high fertility rates are associated to low income and with high participation of women as head of the household. As per marital status, 62.1% (SE=4.4%) reported living in partnership or being married. The contestants had a mean age of 39.7 years (SD=10.8 years), being the youngest 20 and the oldest 68 years old. Considering their ethnic background, 85.1% came from Central Mexico, 12.4% were Garifuna women from Central Americans and 2.5% were South Americans. Among eight categories of diseases listed in our questionnaire, 83.5% had no more than one chronic medical condition.
TABLE 1
Using the Center for Epidemiological Studies-Depression survey (CESD-10), 30.6% (SE=4.1%) were considered moderately or severely depressed negatively impacting their level of daily functioning; depression among Hispanics is often misdiagnosed due to cultural, language and health literacy barriers [40,41]. The use of alcohol and drugs (licit and illicit) was negligible in this sample. Participants’ years of schooling were quite low compared to the US mean of 13.7 years; in our sample, 58.7% had 9 or less years of schooling and the cumulative share of individuals with 12 years or less was 86.8%. Only 13.2% had college education but expressed concerns about finding work, which is likely related to their immigration status. One third of the subjects in our sample spoke a pre-Columbian language and five participants did not know how to read and write in Spanish. While one in three of the interviewed were born or arrived in the US as children or teenagers, acculturation and education levels were quite low. Almost all the participants (93.4%) use Spanish in their conversations at home, whereas 15.7% of them use English for oral communication in daily life and 33.9% speak an indigenous language (Figure 2). Bilingualism of Spanish and indigenous tongues for those raised in rural communities of Latin America as well as Spanish and English for those born or brought in at a young age were common in this study. In line with this result, population data indicates that around 94% of Hispanics and Mexicans born abroad speak Spanish at home, whereas 42% of US born Hispanics and Mexicans use English at home [42].

One in five participants felt discriminated against for being an immigrant, skin tone, appearance, or the way they speak. (Figure 3). Discrimination based on skin tone among Hispanics is well documented and extends to the provision of health care; as a matter of fact, being born in the US and having higher education are not protective against discrimination to access health services [43], which worsens for IMLA. To account for stigma and discrimination, we used the Project on Ethnicity and Race in Latin America (PERLA) color palette to capture self-reported measures of race and ethnicity, ranging from A (darkest) to K (lightest) skin pigmentation. This instrument has been used in several surveys to measure racial discrimination and attitudes [44, 45]. In our sample, 4% self-identified as being in the darkest category whereas 2% as being the lightest; F, G and H skin medium to lighter tones account for 77% of the participants (Figure 4). In this study, skin color varied from Black-Hispanics (Garifuna people, a mix of African and indigenous Latin Americans) to White-Hispanics (Mixtec people who are descendant of Spaniards). Skin tone is important for Spanish American because this feature is perceived as a source of discrimination and is associated with less opportunities for the darker people to get ahead economically and to access health services [46, 47].
FIGURE 3 & FIGURE 4
By the means of a slightly adapted HCHS/SOL V2-Acculturaton survey, we captured different measures of assimilation of IMLA in our sample. These results showed that acculturation is low among our participants (Figure 5). The first five items addressed the use of language to estimate an acculturation index with a mean score of 1.65 (SD=0.12) and the following three items measure the use of media at home with a mean score of 1.95 (SD=0.01). This instrument ranges from 1=Only Spanish to 5=Only English. The last four questions of this survey evaluate ethnic preferences for social interactions, producing a mean score of 1.99 (SD=0.06), responses ranging from 1=All Hispanics to 5=All Non-Hispanics. These low acculturation scores are likely associated with the subject’s place of birth, age of arrival to the US, education, and socioeconomic status. Using the satisfaction with life survey (range 0-3), we found that most of the average scores are closed to 2, which implies that indigenous migrants in NYC are reasonably satisfied with most aspects of life in NYC. The items associated with standards of living, access to public services and housing are likely problematic because of their limited access to quality jobs, low education and legal status as immigrants in the US (Figure 6).
FIGURE 5 & FIGURE 6
To quantify the effects of educational levels, English proficiency and acculturation on income levels, we use a logistic regression as the baseline model. From our sample responses regarding the income level, only 28% had an income above $25,000, as indicated in Table 1. We explored different empirical approaches for identifying the strongest factors that help IMLA to move upward and avoid poverty. Many studies have used logit models along with other machine learning approaches for predicting income [48]. We do not consider a quantile regression because there are no IMLA households with high income in our sample [49]. We considered as poverty line the 20% of the lowest area median income for New York City as defined by the US Department of Housing and Urban Development for a household with at least one child [50]. We first included variables that describe the household characteristics, such as zip code, number of children, and marital status of the survey participant. We assume that the spatial income inequality of IMLA in NYC follows the same patterns as that of the general population. However, we include a dummy variable (Zip Code) that takes the value one when the survey participant lives in an area where the median income is higher than the median income in the whole population in NYC, and the percentage of poverty is lower than the percentage of poverty in the whole population in NYC. The second group of variables includes individual characteristics of the head of household, such as education, skin color, current age, age of arrival to the US, level of acculturation, and physical and mental health. In our logit regression model, the dependent variable denotes households with income above 20% of the area median income, and it is expressed as binary (when households have income $25,000 or more and when households have income less than $25,000). The baseline empirical model is the following:
The first variable in our model is a dummy regarding the household's address, as described above. The second variable is dummy, indicating whether there is a partner, and the variable children indicates whether the family is multi-child with three or more. The variable education indicates an education level of more than secondary. The variable age is categorical, showing the age group of the survey participant. Specifically, it takes the value 0 for an age between 20 and 30, 1 for more than 30 but less than 50, and 2 for an age over 50. The age of arrival shows whether the participant has arrived in the US as a child or an adult. The acculturation variable is the index described above as the average answer to all the acculturation questions regarding language, media communication, and social interactions. Health is the self-reported level of physical and mental health showing at least a health issue regarding cancer, obesity, diabetes, HIV/AIDS, hypertension, liver, or kidney disease.
The PERLA Color Palette is an 11-point chart designed to measure skin color in Latin America, emphasizing darker shades of color. Skin is a dummy variable that indicates whether the respondent reported a non-dark skin tone as characterized to similar studies about Latin Americans that utilize PERLA Color Palette [51]. Ethnicity is a categorical variable that indicates the ethnic background, including Mexico, Central America, or South America. The last variable is the gender of the survey participant. All the results are reported in Table 3 and shows that variables of education, skin, and age are all significant. For the robustness of our model, we tried different specifications; for example, we excluded the variable acculturation because some survey participants did not answer all 12 acculturation questions, and we wanted to increase the sample size in another specification. The variables of education, skin, and age remain significant. As we observe in Table 2, IMLA households who self-report a light skin color are seven times more likely to escape poverty (defined as less than 20% of the area median income). Moreover, an IMLA household with more than secondary education is 12 times more likely to escape poverty. Finally, IMLA who have arrived in the US as children or were born in this country are 13 times more likely to experience upward mobility and be able to escape poverty.
Although the sample size is small, we apply a random forest model to examine whether the significant variables have the highest important scores. We followed a standard approach similar to other studies [52], but without dividing the sample due to its small size. All the variables that we use are binary such as zip code, marital status, children, education, age older than 50, age of arrival, health, skin color, gender, ethnicity (whether the respondent is from Mexico or not). These results are presented in Figure 7. Based on the importance scores the education remains the top determinant of income. Both the logit model and random forest approach support this result, as expected. Although IMLA may not be able to find a job that is suitable with their education level, more educated households are able to make better decisions and eventually help the family to increase its income. Also, the higher the educational level the easier for IMLA to use English to communicate with others.
